Description Erik Schnetter 2004-05-20 11:16:57 UTC 
Version:           3.2.2 (using KDE 3.2.2,  (testing/unstable))
Compiler:          gcc version 3.3.3 (Debian 20040401)
OS:                Linux (i686) release 2.6.6-1-686

I use convert to create either animated gif or mng files from sequences of png images.  I found that the best way to view them under KDE is to type "konqueror filename" in a shell.  When I view the gif animations, konqueror uses about 10% of the CPU time and the animations look smooth.  When I view the mng animations, konqueror uses 100% CPU time and the animations look jerky; I think that it even skips frames.

The animated gifs and the mng files are 540 KB and 470 KB large and contain 80 frames of 640x400 pixels each.
